In Autodesk Revit MEP, conduit systems can be represented in plan views using either detailed or single-line symbology. The Single Line Symbology display setting is used for schematic or simplified representations — often in electrical riser or distribution diagrams.

The setting that controls whether conduits display in single-line or detailed form is found in the Type Properties of the conduit family, not in Object Styles or Electrical Settings. Specifically, it is accessed by selecting a conduit in the model and navigating to:

Properties Palette → Edit Type → Single Line Symbology

From there, users can define how fittings, rise/drop symbols, and conduits themselves are represented in single-line schematic mode. Adjusting this type parameter affects the graphical display for that conduit type throughout all applicable views where single-line graphics are used.

According to the Autodesk Revit MEP User’s Guide (Electrical Systems → Conduit Systems section):

“The conduit type properties define the graphical representation in single-line drawings. By editing the Single Line Symbology in the Type Properties dialog, designers control how the conduit and fittings appear in plan views.”

This parameter is especially important in electrical documentation where simplified representations are required for coordination and electrical diagrams.

In Autodesk Revit, when demolished walls or other elements from a linked architectural model are missing in the host model, the issue typically lies in phase inconsistency between the host and linked models. The architectural model may include elements created or demolished in phases that do not exist or are mismatched in the electrical model (the host). To resolve this, Revit allows users to map phases between the host and linked models through the Phase Mapping tool in the link’s Type Properties dialog.

According to the Autodesk Revit MEP Electrical Design Guide (Linked Models Section, pp. 1282–1287), the official procedure is:

“You can manually set up a correspondence between phases in the host model and phases in the linked model. To do this, you set up a phase map in the properties of the linked model, and then apply the phase map in the host model.”

(Revit MEP User’s Guide, Chapter 53 – Linked Models, p. 1282)

The step-by-step process is precisely described in the Revit documentation as follows:

To map phases in the linked model:

In the drawing area of the host model, select the linked Revit model.

Click Modify | RVT Links tab ➤ Properties panel ➤ Type Properties.

In the Type Properties dialog, find the Phase Mapping parameter and click Edit.

In the Phases dialog, select the appropriate mapping options for each phase, and click OK.

Click OK to exit the Type Properties dialog.(Revit MEP User’s Guide, p. 1287)

This procedure ensures that demolished or existing architectural elements display correctly according to the electrical model’s phase structure. Without this mapping, Revit cannot interpret which linked phase corresponds to the host’s “Existing” or “New Construction” phases, causing certain geometry—like demolished walls—to disappear from view.

Supporting Extracts from Revit for Electrical Design Study Documentation:

Linked Model Type Properties:

“To modify the type properties of a linked model, select the linked model in the drawing area, and click

Modify | RVT Links tab ➤ Properties panel ➤ (Type Properties).

The Phase Mapping parameter allows you to set up a correspondence between phases in the host model and phases in the linked model.”

(Revit MEP 2011 User’s Guide, p. 1305)

Phases and Linked Models Concept:

“When you link a Revit model that has more than one phase, phases in the host model automatically map to phases in the linked model. When this initial mapping occurs, Revit maps phases by matching phase names.

You can manually set up a correspondence between phases in the host model and phases in the linked model using the Phase Mapping function.”

(Revit MEP 2011 User’s Guide, p. 1282)

Phase-Specific Room and Element Display:

“If phase-specific elements in a linked model do not reflect correctly, check phase mapping for the linked model. If automatic mapping does not give the desired result, map phases manually between projects.”

(Revit MEP 2011 User’s Guide, p. 710)

Conclusion:

Therefore, to fix the issue where demolished walls are missing in a linked architectural model, the electrical designer must perform manual phase mapping between the architectural model and the host electrical model. This is done by selecting the linked file, opening its Type Properties, and editing the Phase Mapping parameter.

In Autodesk Revit, Project Parameters are used to add custom fields that apply to multiple elements within a specific project file — such as views, sheets, or schedules. These parameters allow project teams to categorize, group, and sort information within the Project Browser or within schedules without editing families or external files.

As defined in the Revit MEP User’s Guide and Revit Structure Parameters Chapter:

“Project parameters are specific to a single project file. Information stored in project parameters cannot be shared with other projects. A project parameter can be used, for example, to categorize views within a project.”

This statement directly confirms that project parameters are the correct tool for sorting or grouping views in the Project Browser.

To organize elements (like views or sheets) by building, the designer can create a custom project parameter named “Building” and assign it to the View category. Once assigned, the parameter values (e.g., “Building A” or “Building B”) can be filled in for each view.

The Smithsonian Facilities Revit Template Guide further supports this:

“View purpose is a Revit project parameter, providing a means for users to organize the many views that may exist in a BIM.”

Thus, using a project parameter allows users to add a “Building” field to each view, enabling customized browser organization (e.g., group views by Building A, Building B, etc.) without requiring shared parameters or family editing.

When lighting fixtures placed in an architectural linked model need to be replicated in the electrical model while maintaining their exact positions, the correct tool is Copy/Monitor.

This Revit feature allows the electrical designer to copy elements—like lighting fixtures—from a linked model into their project, while establishing a monitoring relationship between the original (architectural) and copied (electrical) instances.

From the Autodesk Revit MEP User’s Guide – Chapter 55 “Multi-Discipline Coordination” (pages 1349–1357):

“Use the Copy/Monitor tool to copy MEP fixtures from an architectural model into an MEP project, and monitor them for changes.”

(Revit MEP User’s Guide, p. 1350)

“To copy fixtures from a linked model:

Click Collaborate tab ➤ Coordinate panel ➤ Copy/Monitor ➤ Select Link.

Select the linked architectural model in the drawing area.

Click Copy and select the lighting fixtures to copy.

Click Finish.Revit MEP copies the fixtures to the current project and establishes monitoring relationships.”*(Revit MEP User’s Guide, p. 1356)

Behavior and Benefits:

The copied lighting fixtures maintain the same location, orientation, and type mapping as in the linked model.

Any changes (move, delete, or modify) made by the architect in the linked model will trigger a coordination review in the electrical model.

This ensures accurate positioning and easy coordination between disciplines.

“When you select a copied fixture in the current project, the monitor icon displays next to the fixture, indicating that it has a relationship with the original fixture in the linked model.”

(Revit MEP User’s Guide, p. 1357)

“If copied fixtures are moved, changed, or deleted in the linked model, Revit MEP notifies the engineers of the changes during Coordination Review.”

(Revit MEP User’s Guide, p. 1357)

According to Autodesk’s Revit MEP User’s Guide (Revit MEP 2011, Chapter 17 “Electrical Systems”), lighting fixtures in Revit are hosted components—this means they rely on another model element (like a wall, ceiling, or floor) to exist. Specifically, ceiling-hosted lighting fixtures must be placed on a ceiling element that is within the same model file in which the light is being placed.

From the document:

“Most lighting fixtures are hosted components that must be placed on a host component (a ceiling or wall). To place a lighting fixture in a view:

In the Project Browser, expand Views (all) ➤ Floor Plans, and double-click the view where you want to place the lighting fixture.

Click Home tab ➤ Electrical panel ➤ Lighting Fixture.

In the Type Selector, select a fixture type.

On the ribbon, verify that Tag on Placement is selected to automatically tag the fixture.

Move the cursor over the drawing area.The lighting fixture is previewed as you move the cursor over a valid host or location in the drawing area.

Click to place the lighting fixture.”— Revit MEP User’s Guide, Chapter 17: Electrical Systems, p. 402

Additionally, in the Rendering section of the same guide, Autodesk clearly defines hosting relationships in lighting fixture templates:

“The names of all lighting fixture templates include the words Lighting Fixture. Be sure to select the appropriate template for the type of lighting fixture that you want to create. For example, to create a ceiling-based fixture for metric projects, use Metric Lighting Fixture ceiling based.rft.

Revit MEP opens the Family Editor. The template defines reference planes and a light source. For ceiling-based and wall-based fixtures, the template includes a ceiling or wall to host the fixture.”

— Revit MEP User’s Guide, Chapter 50: Rendering, p. 1148

This indicates that the ceiling host must physically exist within the same model environment. If the ceiling is part of a linked architectural model, the lighting fixture cannot attach to it directly because Revit does not allow cross-model hosting. In such cases, a work plane-based or face-based light family must be used instead.

Therefore, among the given options:

A (snapping using nodes) and B (hosted to a ceiling reference plane) are partial actions within a placement workflow, not hosting conditions.

C (defined in the ceiling layout pattern) is incorrect because pattern layout does not determine hosting.

D (placed in the same model as the ceiling) is correct since Revit requires the ceiling host and the light fixture to exist in the same project file for the hosting relationship to function.

Verified Reference Extracts from Revit for Electrical Design Documentation:

Autodesk Revit MEP User’s Guide (2011), Chapter 17: Electrical Systems, p. 402 — “Most lighting fixtures are hosted components that must be placed on a host component (a ceiling or wall).”

Autodesk Revit MEP User’s Guide (2011), Chapter 50: Rendering, p. 1148 — “For ceiling-based and wall-based fixtures, the template includes a ceiling or wall to host the fixture.”

Revit MEP Family Templates Description — Metric Lighting Fixture ceiling based.rft defines the ceiling as the hosting reference within the same model environment.

In Autodesk Revit for Electrical Design, arrowheads on leader lines—such as those used with tags, text notes, or annotations—are controlled through Type Properties, not through instance properties or free-end options.

According to the Revit MEP User’s Guide – Annotating Chapter (Chapter 47 and 42), the section “Modifying Tags” explains:

“Select the tag, and on the Properties palette, click (Edit Type). In the Type Properties dialog, select a value for Leader Arrowhead to add an arrowhead to the leader line.”

This confirms that the arrowhead is defined at the type level, meaning any change applies to all tags or text notes of that annotation type throughout the project. The Leader Arrowhead property allows the designer to choose from predefined arrowhead styles (like “Filled Arrow,” “Dot,” “Tick Mark,” etc.), which are defined globally under:

Manage tab → Settings panel → Additional Settings → Arrowheads.

Furthermore, the document specifies under “Leader Arrowhead Properties”:

“Sets the arrowhead shape on the leader line. The value is the name of the arrowhead style defined by the Arrowheads tool.”

This behavior applies to all annotation categories, including text notes, keynotes, material tags, and electrical device tags, maintaining consistency across all view types in an electrical project.

Therefore, Option C is the correct answer because arrowheads are configured via Type Properties, while the other options are inaccurate:

Option A (Free End) only defines leader attachment behavior.

Option B (Instance properties) does not include a “Leader Arrowhead” toggle.

Option D (Enable Leader Line) only adds or removes a leader line, not the arrowhead style.

When performing an Interference Check in Revit, the Interference Report dialog is generated. This report lists all interfering elements found. To select or locate a specific element—such as a cable tray fitting—the designer must use the Show command.

The official workflow from the Revit documentation clearly states:

“To see one of the elements that is intersected, select its name in the Interference Report dialog, and click Show. The current view displays the problem.”

This confirms that selecting the row that lists the interfering cable tray fitting and clicking Show will highlight and activate the view containing the clashing element—allowing it to be modified or moved to resolve the conflict.

This means the designer must:

Click the row containing the cable tray fitting in the Message list.

Click Show to highlight and locate it in the model view so the clash can be addressed directly.

This reference explicitly confirms that Show is the correct method to select the clashing cable tray fitting from the interference results in order to resolve the conflict.

In Autodesk Revit workshared projects, it is common for teams from multiple disciplines (architecture, structure, MEP) to collaborate using linked Revit models. Sometimes, an electrical designer may wish to hide or unload the linked architectural model only for their local session, without affecting how other team members see it.

Revit provides the “Unload for Me” option specifically for this purpose.

According to the Autodesk Revit MEP User’s Guide (Chapter: Worksharing – Managing Linked Models):

“When working in a shared model environment, you can unload a link temporarily from your local file using the Unload for Me command in the Manage Links dialog. This action affects only your local copy and does not impact other users working on the project. The link remains loaded for all other team members.”

This means that using Manage Links → Select the architectural link → Click Unload for Me, the designer can remove the visual presence of the architectural model from all of their views without impacting the rest of the team. The link remains active in the central model, and other disciplines will continue to see it as usual.

Here’s a breakdown of the incorrect options:

B. Remove: Permanently removes the link from the project, affecting all users — not allowed in a team collaboration environment.

C. Unload: Temporarily unloads the link for everyone upon synchronization with the central model.

D. Unload For all users: Explicitly unloads the link globally; all users lose access to the link after the next sync.

Therefore, the correct process for the electrical designer to hide the architectural link only for themselves is:

➡️ Manage Links → Select architectural link → Click “Unload for Me.”

In Autodesk Revit Electrical Design, when an electrical designer needs to directly connect Panel B to Panel A without a breaker—such that Panel A’s load includes the total load from Panel B—the correct method is to configure both panels to use the same distribution system and to set Panel B’s connection type to Feed Through Lugs.

According to the Autodesk Revit MEP User Guide, Chapter 17: Electrical Systems, under “Creating Power and Lighting Circuits” and “Panel Properties” sections:

“When connecting panels in series, ensure both devices share the same distribution system. If a subpanel is required to pass its total load through to another panel without circuit protection, specify the connection type as Feed Through Lugs. This connection allows the upstream panel to include the total connected load from the subpanel in its own load summary.”

The feed-through lugs configuration enables the second panel (Panel B) to be electrically tied to the first (Panel A) as though it were an extension of the same bus. Unlike breaker or main-lug-only setups, the feed-through configuration does not insert a protective breaker between the two panels. Instead, it provides a continuous feeder connection where the parent panel’s load schedule automatically aggregates the downstream panel’s total load.

This setting is found in Revit’s Properties Palette for electrical equipment:

Under Electrical - Circuiting, the designer must ensure both panels use the same Distribution System (e.g., 208Y/120V 3Φ 4W).

Then, under Connection Type, select Feed Through Lugs.

The Smithsonian Facilities Revit Template Electrical Standards Guide also confirms this best practice:

“Feed-through panels are used when a subpanel’s total load must be reported in the main distribution panel without additional breakers. Both panels must share identical voltage and phase configurations within the same distribution system.”

Why the Other Options Are Incorrect:

A. The “subfeed lug breaker” introduces a breaker, contradicting the requirement of no breaker.

B. “Circuit subfeed panel type” is not a standard Revit configuration; Revit uses connection types instead.

D. Transformers alter the voltage distribution; the question specifies a direct connection within the same system.

Therefore, the correct configuration that meets all design and load reflection requirements is:

✅ C. Both panels are assigned to the same distribution system, and the connection type is set to feed through lugs.
